English Guava

Ingredients

Directions

Prepare the fruit

  1. Remove the stalks from the guavas and cut some of them.

  2. Place the guavas in stone jars and add a few imperatrice plums if available.

  3. Put the jars in pans of water and boil them.

  4. Drain the juice and strain it through a jelly bag.

Make the preserve

  1. Weigh the juice and boil it quickly for 15 to 20 minutes.

  2. Stir in ¾ lb of sugar for every lb of juice until dissolved.

  3. Remove any scum and boil the preserve again for 8 to 12 minutes.

  4. Check if it jellies firmly on the skimmer; if not, boil longer.

  5. Pour the finished preserve into shallow pans or small molds.

What each ingredient does

Shepherd's bullace (or other plums)
Provides pectin and acid that help the preserve set into a firm jelly.
Sugar
Sweetens the preserve and, with boiling, thickens the juice and helps it set.

The step that matters

Checking the set on the skimmer. Boiling too briefly leaves the juice runny, while the sugar and pectin need enough concentration to gel. Testing on a cold skimmer shows whether the preserve has reached a firm set before it is poured.
